Peak pulse power capability of 400W with a 10/1000us waveform,  
repetition rate (duty cycle): 0.01% (300W above 78V)  
Very fast response time  
High temperature soldering guaranteed:  
260°C for 10 seconds at terminals  
MECHANICAL DATA  
Case: JEDEC DO-214AC (SMA) molded plastic over passivated chip  
Terminals: Matte-Sn plated, solderable per MIL-STD-750,  
Method 2026  
Polarity: For uni-directional types the band denotes the cathode, which  
is positive with respect to the anode under normal TVS operation.
